7kg*Rs6---- Rs 42
5 kg*Rs4---- Rs 20
6kg*Rs5---- Rs 30
18kg for Rs--92 cost price of 1 kg=92/18=>Rs5.11111
cost of 4 kg ---- 4*5.11111=Rs 20.4444
Profit=12.5%
SP={(100+Gain%)/100}*CP
={(100+25/2)/100}*20.444
=22.95
I hope this is your answer

priya saha  (9 years ago)

price for 18kg mixture(7kg+5kg+6kg)=7*6+5*4+6*5=rs92
so for 4kg=(92/18)*4=184/9
as he made 25/2% profit so add it to c.p to get the amount as
184/9+(25/2)*(1/100)*(184/9)=(736+92)/36
=828/36
=rs23(no approximation needed its a whole no. itelf)

7kg*Rs6---- Rs 42
5 kg*Rs4---- Rs 20
6kg*Rs5---- Rs 30
total mixture---7kg+5kg+6kg--18kg
price of 18kg mixture----7*6+5*4+6*5=rs92
18kg for Rs--92 cost price of 1 kg=92/18
cost of 4 kg----(92/18)*4=184/9rs
as he made 25/2% profit so add it to c.p to get the amount as
SP={(100+Gain%)/100}*CP
={(100+25/2)/100}*(184/9)
=rs23
